Based on this deprecation notice in the docs, looks like the triggers are polling based for the time being.
In the meantime, you could setup notifications to call a HTTP Triggered logic app while being aware of the changes mentioned to them, if they would affect your scenario.
Also, as mentioned in the blog, you could use app tokens to create the subscriptions as they are not affected. Logic Apps uses user tokens (from the OAuth login), which are affected by these changes.
